ATTORNEYS DNJTED HTATEE PATENT @FllilliQlEo VENDING-MACHINE Application led March 13, 1906.

T 0 all whom it may concern:

Be it known. that I, ALBERT E. VYATT, a citizen of the United States, resident of Hoboken, county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Vendin0i\lachines, of which the following is a specification.

My invention relates to machines for vending various articles of merchandise and has for its object to provide a machine of this kind which is simple in construction,vaml which will deliver the merchandise only on the insertion of the proper coin.

My invention will be fully described hereinafter' and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accoinpanying drawings in which Figure l is a sectional view of a machine illustrating a specific embodiment of my invention taken on line lwl of Fig, 2; Fig. 2 is a horizontal section thereof on line 2*?. of Fig. l, and Fig. 3 is a sectional view on the line 2%*3 of Fig. 2.

The mechanism comprises a support L which may be of any suitable construction, to which is secured the casing B with which communicates the customary reservoir tube or chute C. A rotatable carrier D is mounted. on a shaft E which is suitably supported in the interior casing vF. This carrier D is located immediately beneath the open ,end of the chute C, and receives the merchandise to be vended from said chute in the prescribed quantities in the usual manner. As shown in the present instance the carrier D comprises four shelves D each of which is successively brought beneath the delivery end of the chute C and receives one of the packages G which are to be sold. Each of these shelves Dl is provided with a Aflange D2 which prevents the package from being removed from the corresponding shelf in any but the proper direction. The one end of the shaft E projects through the side wall of the interior casing F, and carries a disk H provided on its face with studs or pins H1, the purpose of which will be more fully described hereinafter. A coin chute l is located in a convenient position and is provided at its upper end with an opening l1 in registry with a slot B1 in the casing through which the coin is adapted to be inserted.

J is a slide properly guided in standards J1 secured to the support A and provided with a plunger J2 which extends through the front Specification of Letters Patent.

Patented June 9, 1908.

Serial No. 305,860.

terior casing F has a curved nose L2 which A extends into the coin receiving chamber K, and said lever is further provided with a projection-L3, the object of which will be more definitely pointed out hereinafter. The upper end of the lever L is pivotally connected at Ll with a swinging'arm M having a notch M1 into which normally projects one of the studs or pins H1 of the disk H. The said arm M is further provided with an extension MZ which projects beneath a second pin or stud H1, said arm being maintained in the position illustrated in Fig. l by means of a spring N. A spring O maintains the lever L in its normal position and further acts as a counterbalancing device when the slide J is pushed inwardly.

lf a coin of the proper denomination is inserted through the slot B1 andt he opening Il it will travel down the coin. chute l and drop into the chamber K in which it is held by means of the nose L2 of the lever L. If pressure is now exerted on the push button J3 the slide J will be pushed inwardly and the coin will abut against the lever L and swing it on its pivot L1. After said lever L has been swung a certain distancevthe nose L2 will cease to act as a support for the coin which will drop through the chamber K into the coin receptacle, through a suitable opening in the support A, the projection L3 serving as a coin ejector' in this instance. During this rearward movement of the slide and the swinging of the lever L the arm M will be carried forward and the notched. end will abut against one of the studs H1 and thus rotate the carrier D on its axis E and discharge one of the packages Gr into the delivery chute P from which said package may be removed by the purchaser. As the carrier D is ro tated by the means just described, the pin H1 which follows the one engaged by the recessed end of the arm M will abut against the upper edge of said arm. and act as a stop to prevent the carrier from being rotated too -far and delivering more than one package at a time. The packages are successively guided into the delivery chute by means of j tacle in the same manner as just the member' Q which is pivoted at Q1 to a suitable support secured to the casing F, which member' Q is maintained in Working position by means of a spring Q3.

It will be readily seen by referring to Figs.

2 and 3 of the drawings that as soon as a package leaves one of the shelves D1 oi' the carrier D it engages the member Q which is swung on its pivot against the tension of the spring and thus guides the package into the delivery chute I. After the package has passed into said chute the spring Q3 returns the member Q to its ynormal position. The slide J is provided with a shelf J 7 which serves as a closure for the delivery end of the coin chute I when said slide is pushed inward. If a coin is thus inserted into the coin chute while the slide J is in its inner position the said coin'will not be lost to the urchaser but will rest on said shelf J 7 untilthe slide is returned to its normal position by means of the spring J4, whereupon the coin will drop into the chamber K and upon the depression of the plunger J 2 and push button J3 the mechanism will be operated-as before described and a package delivered. This arrangement also prevents the clogging of the coin chute if more than one coin is introduced into the coin chute at the same time. In this case only one coin at a time would be permitted to drop into the receiving chamber K, the succeeding coin being meanwhile held in the coin chute through the medium of the shelf J7.

In order to prevent light weight coins from operating the delivering mechanism a lever R is pivoted at R1 to the side of the coin chute so that it projects into the coin chute in the path of descending coins. At the end opposite to that which extends into the coin chute the said lever is provided with a weight R2 which is not heavy enough to prevent a coin of the required denomination and proper Weight from tilting and passing said lever and entering the receiving chamber K. If however a light weight coin is introduced into the machine, such iron will be unable to swing the lever R aside and the spurious coin will.

roll from said lever through a transverse slot or opening 18 in the rear wall of the coin chute and will drop through into the coin receptacle without operating the delivering mechanism. A magnet Sis suitably secured on a support T adjacent to the coin chute (which, as before stated, is provided in its rear wall with a transverse opening) for the purpose of attracting washers or other iron or steel disks which might otherwise serve as a medium 'for operating the machine. The metal disk is attracted by the magnet as said disk descends and is drawn through the transverse opening 1S in the coin chute and thereafter drops through into the coin recepdescribed with regard to light weight coins. It is thus impossible to operate the delivering mechanism with anything but a genuine coin of the required denomination.

Various modiiications may be made without departing from the nature of my invention as defined in the claims.

I claim and desire to secure by Letters- Patent:

1. In a vending machine, a slide having a coin-receiving chamber, and adapted to move inwardly, means for introducing a coin into said chamber, a pivoted lever arranged to be brought into operative relation with the slide through the medium of the coin, an arm pivoted to said lever and a rotatable carrier 'for receiving articles of merchandise, provided with a plurality of pins or projections adapted to be engaged by said arm, to bring about a partial rotation of the carrier when said slide is moved inward after the lever` and slide have been brought into operative relation through the medium of the coin, the end of said lever being so constructed as to prevent the rise of the coin upon the operation of the slide.

2. In a vending machine, a slide adapted to be moved inwardly and provided with a coin receiving chamber, means for introducing a coin into said chamber, a pivoted lever one end of which extends into said coin receiving chamber, an arm pivoted to the other end of said lever, a rotatable carrier for receiving articles of merchandise, provided with a plurality of pins or projections adapted for engagement with said arm to bring about a partial rotation of the carrier, when said slide is pushed inward after a coin has been introduced into the coin receiving chamber and a projection on said lever adapted to eject the coin Jfrom the coin receiving chamber after the slide has been operated.

3. In a vending machine, a rotatable carrier adapted to receive articles ofmerchandise and provided with a plurality of pins or projections, a pivoted lever, an arm pivoted to said lever and having a projection adapted to engage one of the pins of the carrier and being further provided with an extension adapted to engage another pin of the carrier at the same time that the projection is in engagement with the iirst named pin, and means for causing said lever and arm to partially rotate said carrier through the medium of a coin.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ALBERT E. WYATT.
